Vent-Axia, the leader in low carbon ventilation, has launched the Lo-Carbon NBR dMEV C, a highly efficient de-centralised mechanical extract ventilation (dMEV) unit.
Designed for kitchen, utility, bathroom and cloakroom applications, the Lo-Carbon NBR dMEV C achieves Building Regulations with the quietest sound levels, the lowest number of installed fans required and the most efficient fans on the market.
Developed for housebuilders, it is been tested to the new SAP 10 performance requirement and listed in the PCDB with its exceedingly low Specific Fan Power (SFP) values as impressively low as 0.08 w/l/s and provides near silent operation independently tested as low as 7.4 dB(A).
The Lo-Carbon NBR dMEV C achieves its low SFPs and low sound power levels through its patent pending air pathway design, which promotes turbulent airflow, allowing for a predictable performance curve and ensuring performance can be met.
High pressure development and the silent mixed flow impeller means the Lo-Carbon dMEV C can meet the requirements of many domestic installations without the need to use a traditional centrifugal fan. Featuring a single high efficiency EC/DC motor the fan achieves highest in class efficiency thanks to its axial fan, which consumes a fraction of the energy of the equivalent centrifugal fan – drastically reducing Dwelling Emission Rates (DER).
Featuring a sleek, circular unobtrusive design with a multi-orientation grille, providing a perfect fit in any scenario, the Lo-Carbon NBR dMEV C is IPX5 rated, allowing installation in Zone 1, 2 and 3 and offers 100mm and 125mm models, with variable speed setting for easy installation and commissioning.
The fanโs brand-new control platform provides fully adjustable airflow, meaning wholehouse rates can be achieved easily using fewer fans, delivering increased ventilation rates at the lowest sound levels with the fewest fans. The controls for the NBR dMEV C unit provide fully adjustable, continuous trickle speeds with a boost speed thatโs activated via an integral humidistat or via LS Input.
โThe Lo-Carbon NBR dMEV C was designed to achieve new Building Regulation ventilation rates while improving indoor air quality, using the lowest number of installed fans, and the most efficient and quietest fans on the market, ticking all the right boxes for housebuildersโ, explains Joe Tse, Product Manager at Vent-Axia. โMeanwhile, homeowners will be happy with a highly efficient, quiet fan which does not disturb their sleep if the light is turned on during the night. Installers will appreciate the ease of install and commissioning through its brand-new control platform which provides fully adjustable airflow.โ
Designed to offer a more relaxing environment for the homeowner, the Lo-Carbon NBR dMEV C features an optional delayed start. This patented comfort control option allows the homeowner to enjoy a quiet, peaceful bathroom for up to 20 minutes before the boost activates.
Furthermore, if the light switch turns on and off within three minutes, the boost will not activate. No more disturbing the family if the bathroom light is turned on during the night.
Providing easy installation and quick commissioning, the easy-to-use speed adjustment dial ensures operational speeds are met as required by Building Regulation Approved Document F, while the IPX5 rating of the NBR dMEV C allows install flexibility without the need for SELV, making it ideal for wet rooms of all sizes since it can be installed in Zone 1.
The continuous running, NBR dMEV C range has a switched live connection for external switches/sensors and harmonised control platform.
The continuous running H model incorporates an ambient response humidistat which increases the extract rate if the humidity rises above the point set at installation. The 100mm fan features variable speed settings of 5-26 l/s achieving a minimum noise level of 7.4 dB(A) at 3 metres while the 125mm dMEV C has variable speed settings of 5-35 l/s achieving a minimum noise level of 8.5 dB(A) at 3 metres.
Vent-Axiaโs experienced and knowledgeable in-house engineering team used state-of-the-art Computation Fluid Dynamics (CFD), to ensure that the decentralised continuous mechanical extract fan operates as efficiently and as quietly as possible, whilst also providing easy installation and quick commissioning.
